1.2.1 Block description
RS232 DE-9S Connector
This connector provides the interface for connection a RS232 device. Most PC RS232 ports or other
RS232 adapters are configured for DTE. The S1-A-7001 pin connection allows use of a straight-through
DE-9P to DE-9S cable. The S1-A-7001 can also be connected directly to a mating RS232 port with the
integral thumb-screws.
RS232 Level Shifter
The RS232 level shifter converts the bipolar signalling of RS232 and converts it to 5V logic which is
required by the CANbus Controller.
CANbus Controller
The Microchip PIC18F4680 runs firmware that converts the communication from the RS232 to CANbus
protocol.
CANbus Transceiver
The Microchip MCP2551 converts logic level signals from the CANbus controller to CANbus physical
signals. These signals consist of a differential pair, CAN_H and CAN_L.
DE-9P Connector (Male)
The DE-9P connector is configured in an industry standard (CiA DS102-2) pin-out to provide connection
to CANbus peripherals through standard cables. See
